A semiconductor chip is divided into a first semiconductor region surrounded by pads and a region outside the pads. A memory is arranged at the region outside the pads. A memory arranged in the first semiconductor region and the memory arranged outside the pads are coupled to a bus interface unit via separate memory buses and a selector. The selector is driven by two phase, non-overlapping clock signals. A semiconductor integrated circuit device is provided that can easily accommodate for modification in the memory capacity of the memory and that can transfer signal/data at high speed with a low power consumption, irrespective of modification in bus interconnection length.
